Usefulness of aMAP Risk Score for Predicting Recurrence after Curative Treatment for Hepatocellular Carcinoma within Milan Criteria.

INTRODUCTION: The aMAP score is a prediction model for hepatocellular carcinoma (HCC) risk in chronic hepatitis patients. This study was conducted to elucidate the utility of this model for predicting initial recurrence of HCC in patients within the Milan criteria after undergoing curative treatment. METHODS: Patients with naïve HCC within the Milan criteria (n = 1,020) and treated from January 2000 to August 2022 were enrolled. The cohort was divided into two groups according to the aMAP score (high ≥60, low <60) and then compared for recurrence-free survival (RFS) and overall survival (OS). RESULTS: Comparisons between the high and low groups showed that etiology (HBV:HCV:HBV+HCV:NBNC = 41:79:2:37 vs. 65:589:11:196, p < 0.001), AST (36 vs. 46 IU/L, p < 0.001), and multiple HCC occurrence (15% vs. 22%, p = 0.026) were significantly different. Additionally, median RFS (59.8 vs. 30.9 months; p < 0.001) and median OS (154.1 vs. 83.4 months, p < 0.01) were greater in the low group. As for patients with HCC due to chronic viral hepatitis, there was a significant difference in median RFS between the groups (59.8 vs. 30.6 months, p < 0.001), especially for HCV-positive patients (53.1 vs. 27.2 months, p = 0.002). In patients with HCC due to a nonviral cause, the difference in median RFS between the low (70.9 months) and high (32.0 months) groups was not significant. DISCUSSION: Findings of this retrospective study indicate a significant association of elevated aMAP with worse RFS in patients with HCC caused by chronic viral hepatitis, especially those with HCV. The aMAP score is considered useful to predict not only HCC-carcinogenesis risk but also risk of recurrence following curative treatment.

Comparison of Surgical Resection and Percutaneous Ultrasonographic Guided Radiofrequency Ablation for Initial Recurrence of Hepatocellular Carcinoma in Early Stage following Curative Treatment.

Background/Aim: The SURF trial showed that surgical resection (SR) and percutaneous ultrasonographic guided radiofrequency ablation (RFA) had equal therapeutic effects for small hepatocellular carcinoma (HCC). However, consensus regarding which treatment is appropriate for initial recurrent early-stage HCC remains lacking. This study aimed to elucidate therapeutic efficacy differences between SR and RFA for initial recurrent early-stage HCC. Materials/Methods: From 2000 to 2021, 371 patients with recurrent early-stage HCC (≤3 cm, ≤3 nodules) after undergoing initial curative treatment with SR or RFA were enrolled (median age 72 years; males 269; Child−Pugh A:B, n = 328:43; SR:RFA, n = 36:335). Recurrence-free survival (RFS) and overall survival (OS) were retrospectively evaluated. Results: Although the median albumin−bilirubin (ALBI) score was better in the SR than the RFA group (−2.90 vs. −2.50, p < 0.01), there were no significant differences between them in regard to RFS (median 28.1 months, 95% CI 23.4−50.0 vs. 22.1 months, 95% CI 19.3−26.2; p = 0.34), OS (78.9 months, 95% CI 49.3­not applicable vs. 71.2 months 95% CI, 61.8−84.7; p = 0.337), or complications (8.3% vs. 9.3%; p = 1.0). In sub-analysis for RFS and OS according to ALBI grade revealed no significant differences between the SR and RFA groups (ALBI 1/2 = 28.2/17.5 vs. 24.0/23.4 months; p = 0.881/0684 and ALBI 1/2 = 78.9/58.9 vs. 115.3/52.6 months, p = 0.651/0.578, respectively). Conclusion: This retrospective study found no significant differences in regard to RFS or OS between patients in the SR and the RFA groups for initial recurrence of early-stage HCC after undergoing curative treatment. These results showing equal therapeutic efficacy of SR and RFA confirm the findings of the SURF trial.

Clinical Usefulness of Surgical Resection Including the Complementary Use of Radiofrequency Ablation for Intermediate-Stage Hepatocellular Carcinoma.

Background/Aim: For intermediate-stage hepatocellular carcinoma (HCC) (Barcelona Clinic Liver Cancer [BCLC]-B) cases, transarterial chemoembolization (TACE) is recognized as the standard treatment, while systemic therapy is recommended for TACE-unsuitable HCC. However, because the curative potential is not high, this study was conducted to elucidate the potential outcomes of surgical resection (SR) for BCLC-B HCC cases. Materials/Methods: From January 2000 to July 2022, 70 patients with BCLC-B HCC treated with surgery as the initial treatment were enrolled (median age 67.5 years, beyond up-to-7 criteria 44). Forty-five were treated with SR only (SR group), while twenty-five underwent that with complemental radiofrequency ablation (RFA) (Comb group). Recurrence-free survival (RFS) and overall survival (OS) were retrospectively evaluated in both groups. Results: The median albumin−bilirubin (ALBI) score was better in the SR as compared with the Comb group (−2.74 vs. −2.52, p = 0.02), while there were no significant differences between them for median RFS (17.7 vs. 13.1 months; p = 0.70) or median OS (66.6 vs. 72.0 months p = 0.54). As for those beyond up-to-7 criteria, there were no significant differences for median RFS (18.2 vs. 13.0 months; p = 0.36) or median OS (66.5 vs. 72.0 months; p = 0.57). An acceptable five-year cumulative survival rate (>50%) was obtained in both groups (54% vs. 64%). Conclusion: This retrospective study found no significant differences for RFS or OS between the present SR and Comb groups with BCLC-B HCC. When possible to perform, the outcome of SR for BCLC-B is favorable, with a five-year survival rate greater than 50%.

Factors Related to Sleeping Disorder Due to Pruritus in Patients with Chronic Liver Disease.

Objective This study evaluated cases of pruritus, which is known to be associated with sleep disorder, in chronic liver disease (CLD) patients. Methods Questionnaires were given to 339 enrolled CLD outpatients in winter (November 2019 to March 2020) and again in summer (April to October 2020) (median interval: 104 days). Relative changes in symptoms shown by a visual analogue scale (VAS) and Kawashima's pruritus score between winter and summer were evaluated in Study 1 (n=199), while Study 2 examined the clinical features of patients with sleep disorder based on the results of the second questionnaire (n=235, median age 70 years old; 141 men, liver cirrhosis 37%). Results Study 1. There was a significant relationship in VAS between daytime and nighttime for each season, as well as between winter and summer for each time period (p<0.001). A comparison of Kawashima's pruritus scores for the daytime and nighttime showed no significant seasonal differences (p=0.436 and 0.828, respectively). When Kawashima's score increased, so did the average VAS for both daytime (0:1:2:3:4=0.4±0.2:1.4±0.9:3.0±1.8:5.9±2.1:6.2±2.3) and nighttime (0:1:2:3:4=0.3±0.1:1.4±1.5:3.5±2.3:6.7±2.6:6.9±1.8) (p<0.001 for both). Study 2. Twenty subjects (8.5%) complained of sleep disorder. An elevated FIB-4 index (≥3.07) showed a good predictive value for sleep disorder (p<0.01). The cut-off for the daytime and nighttime VAS values for existing sleep disorder were 1.6 [area under the curve (AUC) 0.901] and 3.4 (AUC 0.931). The respective sensitivity, specificity, and positive and negative predictive values for sleep disorder based on Kawashima's score (≥2) were 0.85, 0.28, 0.10, and 0.95 for the daytime and 1.00, 0.29, 0.12, and 1.00 for the nighttime. Conclusion Intervention against pruritus is recommended in CLD patients with a high Kawashima's score (≥2) in any season, especially with an elevated FIB-4 index.

Easy clinical predictor for low BCAA to tyrosine ratio in chronic liver disease patients with hepatocellular carcinoma: Usefulness of ALBI score as nutritional prognostic marker.

BACKGROUND/AIM: Low branched-chain amino acid (BCAA) to tyrosine ratio (BTR) is known as an indicator of amino acid imbalance. We elucidated usefulness of newly developed albumin-bilirubin (ALBI) score as alternative methods of BTR in patients with naïve hepatocellular carcinoma (HCC) retrospectively. MATERIALS/METHODS: In 842 patients with HCC and without BCAA supplementation (71 years, male 614, Child-Pugh A:B:C = 689:116:37), relationships among BTR and clinical features were evaluated. Of those, 438 patients, with Milan criteria HCC, treated curatively were divided into the high-BTR (>4.4) (n = 293) and low-BTR (≤4.4) (n = 145) groups. The prognostic value of BTR was evaluated using inverse probability weighting (IPW) with propensity score. RESULTS: The low-BTR group showed worse prognosis than the other (3-, 5-, 10-year overall survival rates: 88.9% vs. 86.3%/70.5% vs. 78.1%/38.1% vs. 52.3%, respectively; p < 0.001). Multivariate Cox-hazard analysis adjusted for IPW showed elderly (≥65 years) HR 2.314, p = 0.001), female gender (HR 0.422, p < 0.001), ECOG PS ≥2 (HR 3.032, p = 0.002), low platelet count (HR 1.757, p = 0.010), and low BTR (≤4.4) (HR 1.852, p = 0.005) to be significant prognostic factors. Both serum albumin level (r = 0.370, p < 0.001) and ALBI score (r = -0.389, p < 0.001) showed a significant relationship with BTR. Child-Pugh class B, modified ALBI grade (mALBI) 2a, and mALBI 2b predictive values for BTR were 3.589, 4.509, and 4.155 (AUC range: 0.735-0.770), respectively, while the predictive value of ALBI score for low-BTR (≤4.4) was -2.588 (AUC 0.790). CONCLUSION: ALBI score -2.588 was a predictor for low-BTR (≤4.4), which was prognostic factors for early HCC patients, and at least patients with mALBI 2b might have an amino acid imbalance.

An intact boundary between the tumor and inner hypoechoic layer discriminates T1 lesions among sessile elevated gallbladder cancers.

BACKGROUND: The depth of invasion determines the surgical method for treating gallbladder cancer (GBC). However, the preoperative correct diagnosis of invasion depth, especially discrimination of T1 lesions among sessile elevated GBCs, is difficult. We investigated the utility of preoperative endoscopic ultrasound (EUS) findings for diagnosing the invasion depth. METHODS: We studied a sessile elevated GBC specimen diagnosed as a T1 lesion before developing our study protocol. EUS evidenced an intact boundary between the tumor and the inner hypoechoic layer (the intact boundary sign). To evaluate the potential of using this sign to diagnose T1 GBC as a primary outcome indicator, we retrospectively analyzed patients who underwent surgical resection of sessile elevated GBCs between April 2009 and March 2020. RESULTS: Of the 26 surgically resected sessile elevated GBC specimens, 20 were included and six were excluded due to difficulty in evaluating the overall tumor or layer structure. The Kappa coefficient for interobserver agreement regarding the intact boundary sign was 0.733. The sensitivity and specificity of the sign for diagnosing T1 lesions were 0.857 and 1.000, respectively. CONCLUSION: This new EUS finding could guide the accurate diagnosis of T1 lesions in patients with sessile elevated GBC.

[A case of mass-forming chronic pancreatitis with amputation neuroma-like neurogenesis of the bile duct].

A man in his 40s visited a facility with the chief complaint of abdominal pain;liver dysfunction was detected, and consequently, he was referred to our hospital for further examinations. His medical history was unremarkable. He used to drink alcohol (beer, 1500mL) every day. Magnetic resonance imaging and computed tomography showed stenosis of the distal bile duct and slight dilation of the upstream bile duct. Common bile duct stones and gallbladder stones were not detected. Malignant tumors in the bile duct biopsy were not discovered. The patient underwent subtotal stomach preserving pancreatoduodenectomy. The pathological diagnosis was chronic pancreatitis with amputation neuroma-like neurogenesis of the bile duct.

Interventional endoscopic ultrasonography in patients with surgically altered anatomy: Techniques and literature review.

There are various reconstruction techniques that are used after upper gastrointestinal surgery. In recent years, opportunities for endoscopic diagnosis and treatment have been increasing in patients undergoing gastrointestinal surgery. With the advent of interventional endoscopic ultrasound (IV-EUS), various procedures have been developed mainly for patients in whom endoscopic retrograde cholangiopancreatography is difficult to carry out. Indications for such procedures are expanding. IV-EUS for surgically altered anatomy (SAA) includes EUS-guided fine-needle aspiration, biliary interventions (e.g. biliary drainage, treatment of bile duct stricture, removal of bile duct stones, and the rendezvous technique), and pancreatic interventions (e.g. rendezvous technique after Whipple surgery). In addition, there have been reports of various EUS-related procedures using a forward-viewing curved linear-array echoendoscope that are carried out for postoperative intestinal tract reconstruction. Although interventional EUS is a useful therapeutic procedure for SAA, there are still no dedicated devices, and standardization of the procedure is warranted.

Ultrasonography surveillance improves prognosis of patients with hepatocellular carcinoma.

To examine the effectiveness of ultrasonography (US) for hepatocellular carcinoma (HCC) surveillance, the prognosis of HCC patients who underwent such screening at an expert medical institution or at general clinics were analyzed, as well as those without US surveillance. From October 2006 to December 2014, 872 patients with naïve HCC were enrolled and divided into the surveillance (S)-group (n=398), who underwent follow-up examinations with US, and the non-S group (n=474). The S-group was further subdivided into patients who underwent follow-up surveillance at Ehime Prefectural Central Hospital, an expert medical institution (SE-group, n=189), and those who received surveillance at general clinics (SG-group, n=209). Prognosis and clinical characteristics were analyzed. In the non-S group, the frequency of patients without viral hepatitis (NBNC-HCC) and Tumor, Node, Metastasis stage was greater. As a result, the median survival time (MST) of the non-S group was reduced, compared with the S group (non-S group, 34.1 vs. S group, 68.2 months; P<0.001). Tumor size was significantly different between the SE- and SG-groups (SE-group, 2.0±1.0 vs. SG-group, 2.5±1.3 cm; P<0.001), whereas tumor number (SE-group: 1.5±1.1 vs. SG-group, 1.7±1.2; P=0.164) and MST (SE-group, 72.1 vs. SG-group, 67.1 months; P=0.931) were not significantly different. Surveillance performed at either an expert medical institution or general clinic improved the prognosis of HCC patients. Dissemination of findings demonstrating the importance of surveillance for HCC to all clinicians as well as patients with chronic liver disease is important, and establishment of an effective surveillance strategy for NBNC-HCC is required.

[Marked improvement in renal tubular markers after switching from adefovir to tenofovir alafenamide in a case of Fanconi syndrome diagnosed through high ALP levels].

A woman in her 60s visited our hospital due to elevation of ALP (1357U/L). The patient had been treated with lamivudine (LAM) in 2005, LAM+adefovir (ADV) in 2009, and ADV+entecavir in 2015 for chronic hepatitis B (CH-B). The ALP isozyme was predominantly bone type. Urinary ß-2 microglobulin (MG) and α-1MG increased to 49635µg/L and 64.1mg/L, respectively. Though no fractures were found during bone scintigraphy, the patient was diagnosed with Fanconi syndrome. However, 3 months after switching from ADV to tenofovir alafenamide (TAF), ALP decreased to 856U/L, and urinary ß-2MG and α-1MG decreased to 624µg/L and 6.0mg/L, respectively. Fanconi syndrome should be considered when an increase in ALP is observed in patients treated with ADV, and urinary ß-2MG and α-1MG assays are useful for establishing a diagnosis. Switching from ADV to TAF was an effective therapeutic option.

Combination of Resection and Ablative Treatment for Hepatocellular Carcinoma: Usefulness of Complementary Radiofrequency Ablation.

AIM/BACKGROUND: In HCC patients with multiple tumors in separate segments, monotherapy with surgical resection is often difficult when the estimated residual liver volume after surgery is thought to be inadequate. We evaluated the usefulness of resection combined with low invasive radiofrequency ablation (RFA) for treatment of such cases. MATERIALS/METHODS: We analyzed 115 HCC patients with countable multiple tumors (≤5) without vascular invasion and/or extrahepatic metastasis, and treated solely with resection (SR group: n = 82), or with both resection and RFA (Comb group: n = 33) from January 2000 to December 2017. Clinical characteristics, overall survival rate (OSR), and disease-free survival rate (DFSR) were analyzed in a retrospective manner. RESULTS: There were 88 males (76.5%) and the average age of all patients was 67.8 ± 8.9 years. The average number of tumors and average maximum tumor size were 2.4 ± 0.7 and 4.1 ± 2.1 cm, respectively. Forty-two (36.5%) patients were classified as beyond up-to-7 criteria. The 3- and 5-year OSRs in the SR group were 82.0 and 67.0%, respectively, and in the Comb group were 75.2 and 65.6%, respectively (p = 0.244), while the 3- and 5-year DFSRs in the SR group were 45.2 and 28.0%, respectively, and those in the Comb group were 37.3 and 23.3%, respectively (p = 0.257). CONCLUSION: The combination of surgical resection and complementary RFA may be an effective strategy for treating HCC patients with countable multiple tumors, who are otherwise difficult to treat with surgical resection or RFA alone.

Prediction of risk of falls based on handgrip strength in chronic liver disease patients living independently.

AIM: Falling is known to be associated with cognitive function. We evaluated the relationship between muscle function and falls in patients with chronic liver disease (CLD). METHODS: We enrolled 100 sequential CLD patients without dementia who were admitted to our institution for scheduled treatment from July 2017 to May 2018 (age 71.0 ± 10.2 years; 76 men). All subjects were self-reliant in regard to activities of daily living. On admission, handgrip strength was determined and falls within 1 month of admission were noted. For determining handgrip strength decline (HSD), previously reported values were used (men, <26 kg; women, <18 kg). The relationship between HSD and falls in CLD patients was evaluated in a retrospective manner. RESULTS: Thirty-two patients had chronic hepatitis and 49 had liver cirrhosis (LC) Child-Pugh A, 17 had LC Child-Pugh B, and 2 had LC Child-Pugh C. Twelve (12.0%) had a history of falling, including 8 (26.7%) of 30 with and 4 (5.7%) of 70 without HSD (P = 0.006). The cut-off value for age in relationship to falling was 69.0 years old (area under the receiver operating characteristic curve, 0.668; 95% confidence interval, 0.514-0.821). A fall during hospitalization was noted more often in patients with a history of falling than in those without (16.7% [2/12] vs. 2.3% [2/88], P = 0.018). CONCLUSION: In CLD patients, the presence of HSD and older age might be independent risk factors for predicting a fall. Assessment of handgrip strength could be an effective clinical tool for easily assessing the risk of falling, especially in elderly CLD patients.

Easy surveillance of muscle volume decline in chronic liver disease patients using finger-circle (yubi-wakka) test.

BACKGROUND: Muscle atrophy (MA) and muscle strength decline are important clinical features in chronic liver disease (CLD) patients. An easy to perform MA screening method without need for special equipment would be helpful. We evaluated the usefulness of the previously reported finger-circle test as screening for MA in CLD patients. METHODS: We retrospectively enrolled 358 Japanese CLD outpatients (70.8 ± 10.2 years, male/female = 234/124) who had undergone a computed tomography examination from December 2017 to March 2018, of whom 137 had chronic hepatitis, 169 had liver cirrhosis Child-Pugh A, and 52 had liver cirrhosis Child-Pugh B/C. Bilateral psoas muscle area at the middle of the third lumber vertebra (L3) was evaluated with computed tomography findings, which was performed as a screening of hepatocellular carcinoma, using a previously reported parameter for MA [psoas index (PI): total psoas muscle area (cm2 )/height (m)2 ] [mean PI ± standard deviation (SD) of male patients: 6.50 ± 1.13 cm2 /m2 and those of female patients: 4.30 ± 0.90 cm2 /m2 ]. We then evaluated the correlation between MA and finger-circle test results in these patients. RESULTS: The mean PI values for finger-circle test results Bigger, Just-fits, and Smaller were 5.64 ± 1.34, 5.00 ± 1.25, and 4.83 ± 1.46 cm2 /m2 , respectively, in male patients (P < 0.001) and 4.31 ± 1.06, 3.93 ± 0.97, and 3.42 ± 0.94 cm2 /m2 , respectively, in female patients (P = 0.001). We found that a finger-circle test result in male patients other than Bigger (Just-fits and Smaller) predicted a decline in psoas muscle area of L3 to PI 5.25 cm2 /m2 (sensitivity/specificity 0.619/0.667, area under the curve 0.654, 95% confidence interval 0.583-0.724), which was approximately mean minus 1 SD (5.37 cm2 /m2 ). On the other hand, a Smaller test result in female patients predicted a decline in psoas muscle area of L3 to PI 3.33 cm2 /m2 (sensitivity/specificity 0.740/0.583, area under the curve 0.698, 95% confidence interval 0.583-0.813), approximately mean minus 1 SD (3.40 cm2 /m2 ). CONCLUSIONS: The finger-circle test is an easy to perform and effective screening method for predicting earlier stage of MA in CLD patients without the need for special equipment.

Proposed a simple score for recommendation of scheduled ultrasonography surveillance for hepatocellular carcinoma after Direct Acting Antivirals: multicenter analysis.

BACKGROUND AND AIM: To develop a scoring method using with common clinical data for predicting hepatocellular carcinoma (HCC) development after sustained virological response at 24 weeks (SVR24) after treatment with direct acting antivirals (DAAs), we retrospectively evaluated clinical features of patients who obtained SVR24. METHODS: From October 2014 to December 2017, 1069 hepatitis C virus patients without a past history of HCC, who obtained SVR24 by DAAs at two different areas, were enrolled (the training [n = 484, ChuShikoku-group] and validation [n = 585, Chubu-group] sets). All were examined by ultrasonography as surveillance for HCC at the time of starting DAAs and twice a year after SVR24. We identified three parameters at SVR24, male gender, FIB-4 index > 3.25, and α-fetoprotein level > 5.0 ng/mL, as risk factors for HCC development and gave them point values, with the sum used as After DAAs Recommendation for Surveillance (ADRES) score. RESULTS: In the ChuShikoku-group, the respective 1-/2-year rates for HCC incidence rates ADRES score 0 were 0.0%/0.0%, for a score 1 were 1.1%/2.1%, score 2 were 8.8%/15.9%, and score 3 were 17.1%/28.1%. On the other hand, those respective scores for the Chubu-group were 0.0%/0.0%, 0.0%/0.7%, 7.9%/10.6%, and 19.5%/not available. The c-index of the predictive value for HCC development in the training set after SVR24 was 0.835 while 0.899 in the validation set. Finally, those of the entire cohort were 0.0%/0.0%, 0.5%/1.6%, 8.4%/13.4%, and 18.0%/32.8%. CONCLUSION: The present ADRES score was simple and easy to use and may be useful for predicting risk of HCC development in short term after reaching SVR24 by DAAs.

Relative changes in handgrip strength and skeletal muscle volume in patients with chronic liver disease over a 2-year observation period.

AIM: There are few reports regarding relative changes in muscle function of patients with chronic liver disease (CLD). We examined CLD patients to evaluate relative changes in handgrip strength and muscle volume. METHODS: We enrolled 413 CLD outpatients who underwent handgrip strength measurements in both 2015 and 2017 (age 67.9 ± 10.0 years; male / female = 242/171; hepatitis C virus [HCV] / hepatitis B virus [HBV] / HBV and HCV / alcohol / others = 239/92/4/22/56; Child-Pugh score [CPS] in 2015 [5/6/7/8/9/≥10 = 335/51/12/11/3/1]). Relative change in muscle volume (ΔPI) from 2015 to 2017 was evaluated using computed tomography findings in 230 of the patients, using a previously reported method. Clinical characteristics, as well as relative changes of handgrip strength (ΔHGS) and ΔPI were analyzed. RESULTS: For the patient cohort as a whole, CPS became significantly worse in 2017 (5/6/7/8/9/≥10 = 319/56/13/11/5/9; P = 0.002). In individual patients with CPS decline, serum albumin level was significantly decreased (3.78 ± 0.50 to 3.33 ± 0.61 g/dL; P < 0.001), whereas no decrease was seen in those without such a decline (4.16 ± 0.48 to 4.20 ± 0.44 g/dL; P = 0.028). Furthermore, ΔHGS (-1.4 ± 4.8 [n = 59] vs. 0.7 ± 4.8 kg [n = 354]; P = 0.002) and ΔPI (-0.44 ± 0.88 [n = 38] vs. 0.03 ± 0.64 cm2 /m2 [n = 192]; P = 0.003) were worse in patients with, compared to those without, a decline in CPS. Age was not significantly different between patients with and without handgrip strength decline (66.5 ± 10.3 vs. 65.3 ± 9.9 years; P = 0.256). There was a significant relationship between ΔHGS, ΔPI and relative change in serum albumin (r = 0.161, P = 0.001 and r = 0.225, P < 0.001, respectively). CONCLUSION: Decline in CPS, especially decreasing serum albumin level, showed a significant relationship with muscle function reduction and muscle volume loss.

Muscle volume loss a prognostic factor for death in liver cirrhosis patients and special relationship to portal hypertension.

AIM: We examined the prognosis of liver cirrhosis (LC) patients with and without portal hypertension (PHT) and muscle volume loss (MVL). METHODS: From 2006 to 2016, 346 LC outpatients (PHT/non-PHT = 173/173) were enrolled (median age, 69 years; men / women, 204/142; Child-Pugh A / B, 230/116; and presence of MVL 15.6% in each group) after propensity matching, following exclusion of those with hepatocellular carcinoma (HCC) beyond the Milan criteria and Child-Pugh C. Portal hypertension was defined as positive for significant esophagogastric varices; MVL was diagnosed based on a previously reported index using CT imaging. Overall survival rate (OSR) was evaluated from the viewpoints of PHT and MVL. RESULTS: There were no significant differences in clinical background (age, gender, etiology, presence of HCC [within Milan criteria], or Child-Pugh class) between the groups. Although there was no significant difference regarding OSR between patients with and without MVL in the non-PHT group (P = 0.076, Holm's method), the OSR of patients with MVL in the PHT group was lower compared to those without MVL in both groups (P = 0.017 and P = 0.012, respectively, Holm's method). As a result, the OSR of patients with MVL (n = 54) was lower than the other patients (n = 292) (3- and 5-year OSR, 69.0% vs. 86.4% and 35.8% vs. 74.1%, respectively; P < 0.001). Multivariate Cox hazard analysis showed that positive for HCC (hazard ratio [HR], 2.028; 95% confidence interval [CI], 1.189-3.460; P = 0.009) and positive for MVL (HR, 2.768; 95% CI, 1.575-4.863; P < 0.001) were significant independent prognostic factors for death. CONCLUSION: Muscle volume loss and HCC, but not PHT, were found to be independent prognostic factors for death in LC patients.

Impact of muscle volume and muscle function decline in patients undergoing surgical resection for hepatocellular carcinoma.

BACKGROUND AND AIM: This study investigated the prognostic impact of muscle volume loss (MVL) and muscle function decline in patients undergoing resection for hepatocellular carcinoma (HCC). METHODS: This study enrolled 171 naïve HCC patients treated with resection from 2007 to 2015, after excluding those lacking spirometry or computed tomography findings, who had received non-curative treatments, or with restrictive or obstructive lung disorders. The median peak expiratory flow rate (%PEF) was set as the cut-off value for muscle function decline, and MVL was diagnosed using a previously reported value. Clinical backgrounds and prognosis were retrospectively evaluated. RESULTS: Overall survival rate was lower in the MVL (n = 35) as compared with the non-MVL (n = 136) group (1/3/5-year overall survival rate = 88.2%/81.6%/55.6% vs 91.0%/81.5%/74.8%, respectively; P = 0.0083), while there were no differences regarding hepatic function or tumor burden between the groups. Child-Pugh class B (hazard ratio [HR] 3.510, 95% confidence interval [CI]: 1.558-7.926, P = 0.0025), beyond Milan criteria (HR 1.866, 95%CI: 1.024-3.403, P = 0.042), and presence of MVL (HR 1.896, 95%CI: 1.052-3.416, P = 0.033) were significant prognostic factors. The decreased %PEF group (n = 84) showed a higher rate of postoperative delirium than the others (n = 87) (27.4% vs 11.5%, P = 0.0088). The cut-off values for %PEF and age for postoperative delirium were 63.3% (area under receiver operating characteristic [AUROC] 0.697) and 73 years old (AUROC 0.734), respectively. Delirium was observed in 50.0% (14/28) of patients with both factors, 23.8% (15/63) of those with 1 factor, and 5.0% (4/80) of those without either factor. CONCLUSION: Muscle volume loss is an independent prognostic factor in HCC patients treated with surgical resection, while advanced age and decreased muscle function might indicate high risk for postoperative delirium.

Validation of Newly Proposed Time to Transarterial Chemoembolization Progression in Intermediate-Stage Hepatocellular Carcinoma Cases.

BACKGROUND/AIM: Determination of failure of transarterial chemoembolization (TACE) for treatment of Barcelona Clinic Liver Cancer stage B (BCLC-B) hepatocellular carcinoma (HCC) has become important because of the development of tyrosine kinase inhibitor (TKI) treatment. We evaluated the usefulness and efficacy of the newly proposed time to TACE progression (TTTP). PATIENTS AND METHODS: From 2006 to 2016, 192 BCLC-B HCC patients [median age 72 years, male/female ratio = 149/43, Child-Pugh score 5/6/7 = 106/56/30, albumin-bilirubin (ALBI) grade 1/2 = 64/128, Kinki criteria B1/B2 = 64/128] were enrolled. TTTP was defined based on a previous report and first imaging performed 3 months after initial TACE had been used to obtain baseline images. The patients were divided into three groups according to TTTP (<5, 5-10, and ≥10 months; group I, II, and III, respectively). We evaluated the relationship between TTTP and overall survival (OS) as well as the prognostic factors for death. RESULTS: The median number of TACE procedures was 4 (interquartile range 3-7). There was a moderate correlation between TTTP and OS (r = 0.527, 95% CI 0.416-0.622, p < 0.001). The median survival for group I (n = 78), II (n = 49), and III (n = 65) was 24.6, 34.7, and 49.5 months, respectively (group I vs. group II, p = 0.023; group I vs. group III, p < 0.001; group II vs. group III, p = 0.037; Holm's method). ALBI grade 2 (HR 1.548, 95% CI 1.004-2.388, p = 0.048), alpha-fetoprotein (>100 ng/mL) (HR 1.540, 95% CI 1.035-2.291, p = 0.033), and TTTP (<5 months) (HR 2.157, 95% CI 1.447-3.215, p < 0.001) were significant prognostic factors for death in multivariate Cox hazard analysis. CONCLUSION: In patients with reduced TTTP, especially <5 months, it might be difficult to improve prognosis with a repeated TACE procedures. In such cases, reconsideration of the therapeutic strategy might be needed when possible.

Efficacy of branched-chain amino acid supplementation and walking exercise for preventing sarcopenia in patients with liver cirrhosis.

BACKGROUND/AIM: Sarcopenia is recognized as a condition related to quality of life and prognosis in patients with chronic liver disease, although no useful strategy for improving muscle volume and strength has been established. Here, we evaluated the efficacy of supplementation with branched-chain amino acid (BCAA) administration and walking exercise. PATIENTS AND METHODS: From December 2015 to July 2016, 33 Japanese outpatients with liver cirrhosis were enrolled (median: 67 years, HCV : HBV : alcohol : others=26 : 2 : 2 : 3, male : female=13 : 20, Child-Pugh A : B=30 : 3). None had a history of BCAA supplementation. After calculating the average number of daily steps using a pedometer for a 2-3-week period, BCAA supplementation (protein 13.5 g, 210 kcal/day) as a late evening snack and walking exercise (additional 2000 steps/day prescribed) were started. Body composition including muscle volume was analyzed using a bioelectrical impedance analysis method, and serological data and muscle strength (leg, handgrip) were evaluated at enrollment, and then 1, 2, and 3 months after starting the protocol. RESULTS: The median average number of daily steps was 3791 (interquartile range: 2238-5484). The average period of BCAA supplementation was 2.7±0.7 months. During the period from enrollment to 3 months after starting the protocol, HbA1c and NH3 were not significantly changed, whereas the BCAA/tyrosine ratio improved (4.3±1.35 to 5.24±2.04, P=0.001). In addition, the ratios for average daily steps (1.595, P=0.02) as well as muscle volume, leg strength, and handgrip strength (1.013, 1.110, and 1.056, respectively; all P<0.01) were increased at 3 months. CONCLUSION: BCAA supplementation and walking exercise were found to be effective and easily implemented for improving muscle volume and strength in liver cirrhosis patients.
